Title: Conversion of hydrocarbons
IPC: C10G11/18
Filed: 1966-07-08
Abstract: A process for converting hydrocarbons comprises passing a relatively dilute suspension of catalyst particles in hydrocarbon vapours as an upflowing stream through an elongated conversion zone, passing a portion of the suspension from the exit end of said elongated conversion zone to a separation zone arranged in an enlarged zone to separate spent catalyst particles from partially converted hydrocarbon vapours, passing another portion of the suspension through a by-pass line as a by-pass stream around said separation zone and into said enlarged zone to separate spent catalyst particles from partially converted vapours, combining partially converted hydrocarbon vapours from said separation zone and from said by-pass line, passing said combined partially converted hydrocarbon vapours upwardly in said enlarged zone when conversion is completed and passing converted hydrocarbon vapours through a second separation zone to recover converted hydrocarbon vapours from entrained catalyst particles.  As shown, apparatus comprises a transfer line reactor 10 into which oil and catalyst may be fed, leading into a separation vessel 30 including a rough-cut cyclone separator 24.  Gases leaving the separator 24 are further separated from entrained solids in cyclones 42 and 52. Solids from the cyclone 24 are delivered by way of line 34 below the level of a fluidized bed of particles 37 in the lower portion 38 of the vessel 30. There is a dilute phase of catalyst particles 31 above the dense phase in the vessel 30. By-pass line 124 fitted with valve 126 is provided to by-pass part of the suspension of catalyst particles from the transfer line 10 around the rough-cut cyclone 24 directly into the dilute phase of the fluidized bed.  The conversion of the hydrocarbon vapours is completed in the dilute phase in the vessel 30.  Further refractory feed or cyclo oil from the process may be introduced through line 68 directly into a further fluidized bed of catalyst particles 84 situated within the vessel 30.  Catalyst may be regenerated in the regenerator 98 and recycled to the process.
